Earth Hour Calgary

Earth Hour is a worldwide event to continue the conversation about how limiting our energy use can reduce our impact on the environment.

The city celebrates Earth Hour on the last Saturday of March each year!

On Saturday, March 23, 2024, The City of Calgary joined other governments, organizations and citizens around the world in shutting off the lights for Earth Hour from 8:30 p.m. to 9:30 p.m.

All non-essential and decorative lighting will be turned off in the following locations:

  • Ad Valorem Place
  • All fire stations
  • Calgary Public Building
  • Dartmouth Place
  • Inglewood Bird Sanctuary Nature Centre
  • Manchester Centre Building E
  • Ralph Klein Park Environmental Education Centre
  • The Calgary Municipal Building (Historic City Hall, Administration Building, Municipal Building)
  • Water Centre

In addition, The City of Calgary has partnered with Alberta Council for Environmental Education (ACEE) to deliver the EcoSchools Canada program in Calgary including supporting EcoSchools to complete their action of participating in Earth Hour.

For support, see ACEE's FAQs or contact the EcoSchools in Alberta team. Teachers/Administrators can register their school at any time.
